'HOE.

To all whom it may concern:

Be it known that I, JOHN H. TRIGG, a citizen of the United States,residing at Cor inth, in the county of Grant and State of Kentucky, haveinvented a new and useful Hoe, of whichthe following is a specification.This invention relates to hoes, and more especially to those havinginterchangeable blades; and theobj'ect of the same is to produce animproved detachable connection between the blade and the handle, whichconnection serves also as a handle fastening. This object isaccomplished by the construction hereinafter more fully described andclaimed, and as shown in the drawings, wherein- I j Figure l is ageneral perspective view of this lmplement ready for use. Fig. 2 isavertical central section thereof. Fig. 3 is a perspective detail of theeye member as Fig. 4 is a permember as seen from its inner side. Figs.'5 and 6 are-sec tions on the line 55 and 6-6 in Figs. 1

and 4 respectively. Fig. 7 'is an elevation of a slight modification.

In the drawings the letter H desi ates the handle which is preferably ofwoo and my invention contemplates no change in this handle excepting toborea hole it through it near "its outer end. On said end is mounted theeye member best seen alone in Fig. 3, which member comprises a tubularsleeve 4 and an integral spur projecting downward from thesame near itsouter end. The sleeve has a bore into which the handle H may be insertedas best seen in Fig. 2, and at right angles to this bore it has aperforation 5 for a purpose to appear below. The spur is by with themetal of the sleeve, and is 'rather thick at its upper portion wherewitmerges into said 'slee-veas seen at 6 and is y prefer ence ofrectangular cross sectional contour as seen in Fig. 5, while its lowerportion 7 is cut away on its outer face. for about half the thicknessofthe upper portion so that it will be thinner,- and in contour it is\/-shaped in elevation because its sides. 8 converge to a sharp edge orpoint 9. Over this pointand in the thicker portion 6 is formed.

an inverted V-shaped notch 10 ,whose side walls are undercut or beveledas. at 11, as also by preference are the shoulders 12 be-' tween thethicker portion 6 and the lower a portion 7 ,whereas the side edges 8of'said preference formed integral Patented July 4,1911. Serial No.612,775.

lower portion 7 are by preference beveled in the opposite direction.

The blade member best seen alone in Fig. 4, comprises a body 20 which wemay call the tool proper, being shown as a hoe blade in that view and asa rake in Fig. 7 although it will be clearly understood that a number ofimplements or tools may be provided, each having the same fasteningmeans as those to be next describedhence where I speak herein'ofthisdevice as a, hoe it is to be understood'that I use the term broadly ascovering any equivalent agricultural implement. It is essential that theupper por- 'tion of the body 20 shall be a flat blade as seen at 21, andin its upper edge are cut two notches 22 each of which preferabl has astraight vertical'outer wall 23 adapted to stand against the sideedgesof the thicker portion 6 as seen in Fig. 1, and an inclined andtransversely beveled inner wall 24 adapted to engage the undercut edge11, the convergence of these Walls being such that the material of theblade 21 between them 00- cupies and completely fills the notch 10 whenthe parts are assembled. 'From the apex of this porticnof the blade, arod 25 projects upward and is by preference formed integral with thematerial of-the tool, the length of this rod being such that it willpass through the perforation 5 in the sleeve,

4 and through'the hole It in the handle H referred to above, and willproject upward beyond the top of the sleeve where it is threaded as'at26 to receive a nut 27 for holding the parts. together. This detail,therefore, serves not only to hold the metal parts of this hoe connectedwith each other, but also as a handle fastening to the sleeve 4 thehandle H, and it will be impossible for the latter to become loose solong as the nut 27 is not removed. The

lower ends of the notches 22 are beveled as at 28 to fit theundercut'shoulders 12. On the inner side or face of the blade 21 areformed lugs 30 whose adjacent edges diverge upward and are undercut asat 31 to conform with the divergence and beveling of the sides 8 at thelower portion 7 of the spur. By preference these lugs are formedintegral with the body 20 of the blade 21,

and in fact the entire blade and rod 25 can be'made of one ting edge (orits teeth as shown in Fig. 7)

suitably tempered to perform the work which the implement will be calledupon to hold within piece with its lower or cutdo. As a modification Imay omit the lugs 30 shown in Fig. 4 and substitute a single lug 40 withundercut upper edges 41, but in this case I shall provide a notch 42 inthe extremity of the lower portion 7 of the first described member andthe edges-of this notch will of course be beveled to correspond withtheundercut edges of'the lugs 40.

It is to be understood that this implement is furnished to the consumerwith one handle, one sleeve, and a number of tools comprising a bodyshaped to. perform what work he desires and including a bladehaving thefastening means described and which into the perforation 5 in thesleeve/t, and

cooperates withthe fastening means on the spur portion of the sleeve. Inorder to assemble these various parts, the user inserts the threaded end26 of the rod 25 upward then turning the body 20 so that the blade 21lies against the face of the lower portion 7 of the spur, he raises theentire blade until the undercut edges of the lugs 30 (or the undercutedge of the lug 40) engage said lower portion, at which time the notches22 will engage the upper portion 6 of said spur,

and the latter will beheld as one with the tool. Meanwhile the rod 25has. passed through the hole in the handle Hand upward through the upperend of the perforation 5, and the final act is to apply and tighten upthe nut'27, thereby drawin the parts still more firmly together an ofcourse preventing the dislocation of the handle as long as the nut is inplace. It will be found that the various points at which the twometallic'members make close contact with each other will not only giverigidity I to the entire implement and resist the strains which arebrought upon it by its constant use, but will prevent dirt and otherparticles from entering between the meeting faces of the metallicmembers and rusting therein.

As above intimated, I do not confine my-' self to the shape of the tool,nor to the sizes.

above the sleeve to permit the insertion be neath of a wrenchsq as toturn the nut 27. In implements of this character it is well known thatthe soil and mud often, get onto the nut and into the threads'26 tosuch-an extent that the nut cannot be removed when desired, and I havefound that a protector of this kind is extremely serviceable at thispoint. e
